7. In cold weather or when the tool has not been
used for a long time, let the tool warm up for a
while by operating it under no load. This will
loosen up the lubrication. Without proper warm-
up, hammering operation is difficult.
8. Always be sure you have a firm footing.
Be sure no one is below when using the tool in
high locations.
9. Hold the tool firmly with both hands.
10. Keep hands away from moving parts.
11. Do not leave the tool running. Operate the tool
only when hand-held.
12. Do not point the tool at any one in the area when
operating. The bit could fly out and injure some-
one seriously.
13. Do not touch the bit or parts close to the bit
immediately after operation; they may be
extremely hot and could burn your skin.
14. Some material contains chemicals which may be
toxic. Take caution to prevent dust inhalation
and skin contact. Follow material supplier safety
data.
SAVE THESE INSTRUCTIONS.
WARNING:
MISUSE or failure to follow the safety rules stated in
this instruction manual may cause serious personal
injury.
OPERATING INSTRUCTIONS
Installing or removing battery cartridge (Fig. 1)
• Always switch off the tool before insertion or removal of
the battery cartridge.
• To remove the battery cartridge, withdraw it from the
tool while sliding the button on the cartridge.
• To insert the battery cartridge, align the tongue on the
battery cartridge with the groove in the housing and slip
it into place. Always insert it all the way until it locks in
place with a little click. If you can see the red part on
the upper side of the button, it is not locked completely.
Insert it fully until the red part cannot be seen. If not, it
may accidentally fall out of the tool, causing injury to
you or someone around you.
• Do not use force when inserting the battery cartridge. If
the cartridge does not slide in easily, it is not being
inserted correctly.
Switch action (Fig. 2)
CAUTION:
Before inserting the battery cartridge into the tool, always
check to see that the switch trigger actuates properly and
returns to the "OFF" position when released.
To start the tool, simply pull the trigger. Tool speed is
increased by increasing pressure on the trigger. Release
the trigger to stop.
Reversing switch action (Fig. 3)
CAUTION:
• Always check the direction of rotation before operation.
• Use the reversing switch only after the tool comes to a
complete stop. Changing the direction of rotation
before the tool stops may damage the tool.
• When not operating the tool, always set the reversing switch lever to the neutral position.
6
This tool has a reversing switch to change the direction of
rotation. Depress the reversing switch lever from the A
side for clockwise rotation or from the B side for counter-
clockwise rotation. When the switch lever is in the neutral
position, the switch trigger cannot be pulled.
Selecting action mode
Rotation with hammering (Fig. 4)
For drilling in concrete, masonry, etc., depress the lock but-
ton and rotate the change lever so that the pointer points to
the H symbol. Use a tungsten- carbide tipped bit.
Rotation only (Fig. 5)
For drilling in wood, metal or plastic materials, depress
the lock button and rotate the change lever so that the
M
pointer points to the
wood bit.
Hammering only (Fig. 6)
For chipping, scaling or demolition operations, depress
the lock button and rotate the change lever so that the
X
pointer points to the
chisel, scaling chisel, etc.
CAUTION:
• Do not rotate the change lever when the tool is running.
The tool will be damaged.
• To avoid rapid wear on the mode change mechanism,
be sure that the change lever is always positively
located in one of the three action mode positions.
Installing or removing bit
Important:
Always be sure that the tool is switched off and the bat-
tery cartridge is removed before installing or removing
the bit.
Clean the bit shank and apply the bit grease provided to
it before installing the bit. (Fig. 7)
Insert the bit into the tool. Turn the bit and push it in until
it engages. (Fig. 8)
If the bit cannot be pushed in, remove the bit. Pull the
chuck cover down a couple of times. Then insert the bit
again. Turn the bit and push it in until it engages. (Fig. 9)
After installing, always make sure that the bit is securely
held in place by trying to pull it out.
To remove the bit, pull the chuck cover down all the way
and pull the bit out. (Fig. 10)
Depth gauge (Fig. 11)
The depth gauge is convenient for drilling holes of uni-
form depth. Loosen the clamp screw and adjust the
depth gauge to the desired depth. After adjusting, tighten
the clamp screw firmly.
NOTE:
The depth gauge cannot be used at the position where
the depth gauge strikes against the gear housing/motor
housing.
Side grip (Fig. 12)
CAUTION:
Always use the side grip to ensure operating safety when
drilling in concrete, masonry, etc.
The side grip swings around to either side, allowing easy
handling of the tool in any position. Loosen the side grip
by turning it counterclockwise, swing it to the desired
position and then tighten it by turning clockwise.
